You need the coöperation of the ISP(s), but what you can do is get PI space, run BGP on your router, and use a private ASN (64512-65534) to advertise to your ISP, and then your ISP advertises to the world with their ASN.
One common scenario is two links to the same ISP, so everyone knows which link is active (you can do active-active (load balancing/sharing), or change weights or local preference for active-passive):

* https://learn.nsrc.org/bgp/two_links_one_isp_load_balancing
The whole BGP process with a private ASN that the ISP strips out and replace with their own ASN on the Internet is how "BYOIP" (bring your own IP) usually works.

One thing I find slightly confusing/frustrating about IPv6.
You're discouraged from using ULAs (basically the equivalent of private addresses from v4) as they'd rather you use GUAs. But you get your GUAs from your ISP normally, which means if you change your ISP you need to renumber your network. They also generally frown on NPT66. So the supported solution is to get PI space. But to get PI space you need to have an ASN first, which requires you to have public peers, which are you just expected to get someone to peer you and then just firewall all the incoming traffic? These seems to be the one option for stable addresses on a IPv6 network that is not vaguely disapproved of.
Or what people actually do is avoid all that complexity and run IPv4 locally and use RFC1918 addreses NAT46, which seems like a self inflicted defeat to the IPv6 first aims of the IETF, IANA and the RIRs.
You don't actually need an ASN to get PI though? You can use PI just fine with BYOIP. Actually... I don't think you are even required to announce them on the Internet.

ARIN NRPM 4.10 has special provisions for getting new IPv6 only ASNs under an org with no IPv6 addresses an IPv4 block to facilitate your IPv6 only network via NAT64 as well as hosting core services like DNS dual stacked (which you probably would do if getting your own ASN :)).
In regards to peering the Vultr VPS option allows dirt cheap VPSs to peer so I'd recommend checking them out first.
Question to the crowd: what's a cheap good way to get a peer for full tables? Vultr is restrictive on that, sensibly so, but it was nice/fun having my own looking glass. I used to have it with a $150/m quarter rack Colo but after my home internet went 5 gig symmetrical it seemed like a massive waste to maintain a remote Colo so I dropped that.

Note that ARIN NRPM 4.10 now requires the requested range to be used exclusively for IPv6 transition and not anything else.
As for full table, several providers I recommended in the original post are able to do a full table for less than $10/month. You can also join an IX and ask nicely for transit from other members. Some may even offer you free transit the moment you join.
I also use Decimal Time and the French Republican Calendar as my default calendar and time method. The mental math to convert back to "standard" time and date is very easy once you get the hang of it, and I think it's good practice to not take for granted systems we consider "standard" such as time.
For more on the philosophy of this, I highly recommend Jenny Odell's Book, Saving Time. Note that she doesn't talk about the revolutionary calendar in it (to my memory) but touches on a lot of the realities of time and clocks themselves.
I am curious which leap day system you use for the French Republican calendar. Most popular versions of the calendar I see floating around just use the Gregorian leap year system, which I don't like because it yields the wrong results in the year the calendar was in use. Yet, I don't see mental math as a viable option when using the original date-of-equinox method used during the revolution.
It's actually surprisingly easy to get an ASN for yourself and speak BGP. If you find building something like this tool interesting, you should give it a try. I wrote an introduction of sorts earlier (https://qt.ax/asn) if that interests you.
