There is one (inactive) listing on open corporates with bankeer in the name, so at least one other person in the history of mankind has thought of this name.
There’s also a handful of names with some version of this in the domain.
If you can get it on a brandable marketplace I can see this listed for 3-10k. Probably liquid for a tiny fraction of that and you’re in for a lifetime of autocorrecting, but not terrible as far as brandables go.
