Dreadwing Termis with Moirat?

Ok, i got a stupid idea: can i take a (servo armor) Moirat with cool guns, no Jump Pack and maybe great sword. Put him into a unit of bolter, mace Terminator? Dreadwing for fluff and against plasma?

And than have a cool anti servo armor unit with Rad graneds so insta kill energy weapons?

I know just take knights would be better, or claws and just more attacks and rerolls, But i have so many of those termis and just got the special weapon arm Set for them, and a cypher 😅
