A Theoretical Question (Helix LT)

I run my Helix LT into the Return of a Peavey Classic 50 2x12 with 25w Greenbacks. The Power Section the Peavey is 4 EL84 tubes. If I run an AC30 Preamp model into the Peavey power section, is it a 1:1 exact copy of an AC30, which also has 2x12 Greenbacks and 4 EL84 tubes?
