Yeah, I was wondering how you intended for the format to play out, because in the example given, being able to play multiple override pieces would be broken and unfair, if your opponents don't have any door control at all. It would basically force people into playing squads with access to Override, thus greatly limiting the options.
Maybe play it as a kill-em-all format, rather than standard tourney rules.
Looks like the 18 and 20 point ranges could be pretty decent as well. At 18 points you have things like Nyna, Bomo, TBSV, Jedi Healer, R2PO, Jar Jar, Arden Lyn, Lando DS... At 20 points you can run Vong JHs, Disciple of Ragnos, Yoda FS, Cade Padawan, Whorm, Dark Trooper Phase II, Bodyguard Droids, Commander Gree.
Seems like, overall though, this would be one of those formats where it would be most beneficial to run the higher point characters. Something like, 45 points (Mara Jedi, Snowspeeder, Jensaarai Defender), as it is just simply difficult for the cheap pieces to even hit the bigger guys. Comes down to number of dice rolls though, I guess. Mara would likely give the ERC squad a run for it's money all on her own, as the Stealth would keep her from getting hit at all early on, and then she can kill at least one ERC every turn. Go after Crix first (if possible), and it makes it even easier.
Still though, sounds like a fun format. 49 points looks like a sweet spot as well with pieces like Malak DLOTS, Luke COTF, Tyranus DLOTS, Maris Brood, General Solo, or The Exile.
