I think TJ's have a door surround that would suit your purpose, I'm not sure whether its for the factory soft top or bikini of some type, but it looks to seal up against the full doors and bikini style tops with much less gap.
I have no idea how they attach, but i'd assume some minor fab work would have you fixed. perhaps some better velco would help too.
