I don't know what dose level you are on, obviously, but if I tripled my Spiro most likely it would burn a hole through the lining of my stomach. Be careful, hey?
As long as you are still taking enough Spiro to suppress your T, you aren't going to get any reversion of changes. You'll just stop getting more changes until you are back on E and it has built up in your system again.
Skipping Spiro is actually more dangerous if you are worried about going back to looking like a boy. It's the testosterone that would cause that, not the lack of estrogen.
