Yes, if you have that much skillspeed, you'll be able to get an 8th weaponskill in all other openers as well, In the one I posted, it'll be an extra Clean Shot at the end.

Whether the extra weaponskill in Wildfire outweighs the loss of other stats (det in your case) overall is a different matter, but I don't feel qualified to look into that right now. If it works for you, then go for it.
