The advantage of the soft top is that you can slide it around a bit. Mine was much more forward before I added a Superatv flip up shield, had to move it back some so it wouldn't interfere. I'd bet you could get it to work with some tweaking of the lights too. Plus, it's not like you're dropping $400 for a hard top.
The bimini top won't fit properly, but you can stretch it around your lights, or simply unbolt the lights from the bracket, cut slits in the bimini top and bolt the lights back up, that's what I'd do.
One of these days I'll find a picture of a P500 towing a P1000, and I'm going to flood this place with it!!! lol (PS: I searched everywhere, there are none... )
