Trial NLH tournament strategy

[MtnDave]

Mainly based on my years of O8 playing, where slow playing is rarely a good idea, I am thinking of experimenting with the following NLH tournament strategy:
I call this the never-limp strategy.
A) Early in the tourney:
1) In early position, always open 4xBB
2) In mid-position, always open 3 to 3.5 BB
3) In late position, always open 2.5 to 3 BB
B) Mid-tourney
(Basically the same, but adjust bets according to stack sizes. Raises may be a bit lower.)
C) Late tourney - always raise if entering a pot, but raise size depends on stack sizes.

Note: explictily am not specifying hand values - think Harrington on Holdem ranges.
Note: if there is a bet or limp in front of me, adjust according to the gap concept, but again, never call.

What do you all think? How much equity am I giving up by NEVER limping when being first in? But I am betting my draws the same as my monsters.
