Is it profitable? easy to answer: the number of tables is not relevant. First you have to determine if it's profitable at all. If it is in 1, it'll be in 30. Multitabling only multiplies the result...if it's a losing strategy on 1 table, it'll be 30 times as losing on 30 tables.
For the numbers. You're playing 1.4% of your hands. That means you play about 1 hand in 70!
That means you play, on average, once every 8 orbits or so (closer to 7.7).
So you'll be paying 8*1.5 BB = 12 BB to play a single hand. And when you do, why do you expect to win anything most of the time? although most micro stakes players call too often, I can assure you the vast majority of them does NOT call a preflop all in without a monster hand very often (although they sometimes do). That means you'll most often won't be called at all and win only the blinds, and you'll lose 8 times that till the next hand...
so you'll be called only after pushing a few times (on average) and already losing dozens of BB (and that's on a loose table. a direct preflop all in may not be called at all for many times. So you could conceivably expect to lose close to a whole buy-in before anyone calls you!)
and when you DO get called, most (granted, not all), of the times you'll run into other monster hands. Especially the QQ, will often run into AK, KK, AA, two of which crush it, and it is only a very slight favourite vs. AK.
Considering you already have to make up for a deficit of many dozens of BBs from the times you weren't called, and your equity often isn't really sky high when you do get called with QQ, and probably often run into very high A hands (from looser callers in these limits) with KK which still have 30% against you...
So...this strategy is either sure loser, or a horribly weak winner (against a table of maniacs you could get a low winrate).
playing it on 30 tables will just mean accumulating these losses 30 times faster
NOT recommended.
However, extending the hands you play a bit, and playing with the stack size and sometimes going all in on the flop instead of preflop, as the circumstances dictate, would lead you to the Short Stack Strategy on pokerstrategy.com's strategy articles. It's not much more complicated than what you've described... Just not THAT simple.
Good luck
