I'm always interested in someone willing to do conversions (all the D20 material out there - so little time to convert). I do not like D&D as a system, but I do like some of the support material which I do sometimes bring into Rolemaster.
As for Paizo, I like their stuff. Along with Green Ronin, they have some great source books and ideas - unfortunately it is centered around D&D 3.5.
A little side story. Recently I was invited to join a 3.5 game and I accepted (hey I do not have to be the GM for once). The GM is starting me at 3rd level since most of the group is fourth level. That is when I remembered one of the things I really dislike about D&D, the levels are so unbalanced. In Rolemaster a 1st level character could easily join with a group of 4th level characters. I had one game where the difference was 8 levels between the highest and lowest character. Sure you have to play smart when your level difference in a group is high and your on the low end, but it is duable. D&D - your canon fodder.
Anyway, I always like to see good stuff ment for D20 converted to Rolemaster.
