Need EV calculation/strategy variations (Hi/Lo-I18) on church BJ game.

A local church is having their annual Fall Festival. The BJ that they deal is as follows:

6 Deck, 5 1/4 Decks Pen, BJ pays 2:1, DD 10/11 only, Split/Resplit, No DDAS, No Insurance, S17, Dealer takes Ties on 17-19, Pushes on 20-21, $2-$10 Spread.

I understand that the EV is severely negative on a "house takes all pushes" game. Just wondered if this modified game has any merit (especially with the 2:1 BJ and deep pen). Thanks in advance.
