I'd be strongly in favor of not showing 2nd negatives after 2c-2d-3c with long hearts, or spades for that matter. Just bid 3h/3s and get to game and try to make it. I don't think limiting the hand with 3d is worth it, it's not like you can bid 3d then 3h and end with a partial. And it's not like guaranteeing 4-7 with long hearts is really going to enable one to reach a lot of slams.
Just bidding 3h with long hearts regardless of strength would allow opener to bid 3nt without a heart stopper and try to make it, and with really long hearts can pull 3nt to 4h.
I think 2nd neg should only apply after 2c-2d-2M. Over 3m you need all the bids to intelligently bid the right game, and it's really almost impossible to stop in partial anyway. 2c openers with minor should be stronger than with major anyway, since 5m require 11 tricks.
