I've been using vim user for about 10 years and a colemak user for probably 9 years. At first I remapped the hjkl keys to maintain the muscle memory for movement, but ended up going down the rabbit hole of remaps. Eventually I gave up and reverted to the default keybindings. At first it was weird, but after a month or so I got used to it.

I would definitely advise against remapping vim bindings. The first is because if you ever has to use vim on a non-colemak machine, figuring out the keys will be very painful. Secondly because vim has influenced a lot of other programs (man, less, gvim, etc) and most of them are much harder to rebind if they even support it at all.
