Seeing the interest and potential commercial value in these basses, I think I'd recommend getting some real expert opinion on this, before committing. Obviously, if it's only for playing it yourself, you can get it to suit your style, no problem. If, however, it wipes out a large chunk of a possibly high 'collector's' value, then it may be worth either learning to play 'as is', or keeping as an investment, but playing a 'lesser' bass.
Just my (inexpert...) tuppence-worth, hope this helps.
