Question about new Pokerstars micro $1.20 5-table SNGs

[cognito20]

Having just done my annual cashout for our (my wife and I) summer vacation (I mostly play poker to make money for "extras" for us throughout the year), I have deposited $50 into my Poker Stars account. Having not played in a month, I couldn't help but notice they're now offering $1+0.20 buy-in 5-table NL SNGs. I am a relatively new NL player who has read Harrington HOH1 and HOH2 and try as much as possible to incorporate the concepts into my play (starting hand standards, use of the continuation and probe bets, recognition of inflection points and Yellow/Orange/Red Zone play, etc.). I have cashed in 7 or 8 $10 buyin or below NL MTTs on Stars (no final tables, although I was the chip leader in a WCOOP Round 1 satellite when the cutoff point came), and am net-plus in the $5.50 NL single-table SNGs there. I also am a +3.76 BB/100 limit cash game player (albeit in a small sample of 11K hands), although I stick to Party Poker for that because of the much softer action.

My question is, despite the 20% vig, can someone of my background, playing Harrington's system or a reasonable variant therefore, expect to be able to beat these $1.20 5-table SNGs and use them as a bankroll builder? And if so, do you think my 41-entry fee bankroll is enough to overcome variance? Thanks for any help you can give.
