Smoothest possible transition from combat to subtlety

Hey guys, so I got my rogue to 40 and while I’ve had a blast, I’ve realized that I don’t absolutely adore the fact that I’m a rogue rocking two swords huge swords lol. Sounds silly and maybe combat is the meta. However, I wanna take on the true rogue vibe and possible switch to subtlety. What I’m wondering, especially since I JUST got two wicked swords (vanquisher and serenity) is how difficult it’d be to switch specs and gear up.

Would it be worth it, would it throw off my game entirely or would a couple green daggers tie me over till I run some dungeons and get some half decent daggers, what are some pros cons etc? I’m open to all advice as I’m a pretty new player, thanks!
