With 125 attack though, Skarmory normally takes neutral damage, and if it chooses to Roost it could be potentially ko'd even with the attack drop.
It'd be interesting to see who Conkeldurr gets paired up with. Hmm... Maybe Aggron ? Conk could appreciate the defense boost at the cost of lower attack. The reason I'm suggesting this is that giving Steelix's stats to Aggron doesn't really change him much, because Rock/Steel gets KO'd by a lot of things anyway and it can't do anything yet with 85 base attack. With Conk's stats, it gets better attack, it does lose its great 180 base defense but it's a horrible defensive typing anyway. It doesn't have any form of priority, so it wouldn't be OP either. Just a suggestion. Conk would be a solid tank with 180 defense and 110 attack, weaker attack means weaker priority as well, and it still can't take special hits well so it wouldn't be broken either.
Tauros' stats is basically a bulkier Conkeldurr, which is nice, but it's fantastic speed is now gone, and it can't take special hits even neutral with 55 SpD. At least Rhyperior had Solid Rock. Rhyperior on the other hand could use a nice Solid Rock boosted 70 SpD better than before, but with two 4x weaknesses it's still dead. 110 speed and 100 attack is good though.
