Not a problem. It will require a different engine mount, some tail beefing and a tail wheel and tail spring, different main gear legs and a modification of the lower cowl as the main component changes. Remember also that the low points in the fuel tanks will be different. Might make sense to put new fuel drains in at the rear side of the tanks when converting to the tail wheel configuration. there are avery few other changes that can be done easily. the cowl and prop spinner will mate just a bit further apart after the conversion, but no big deal.
