You should get an "easy setup" pool/pond, then you can control it, you have more space, plus then you could see if it works.
And by "plakat aka wild types" more than long finned, I am just pointing out that I have noticed that bettas with longer fins have a harder time getting along than short finned bettas like the wild type. Yes a few fish may "be able to be together" but it depends on the particular betta, the space, and how heavily planted you really want it. IMO of course, but sure, go with long fin short fin whichever you want. Trial and error.
