I recall seeing from Burgess 2. Nc3 Nf6 3. g3 (and on 3...Bb4 4. e4), ...
1.c4 e5 2.Nc3 Nf6 3.g3 Bb4 4.e4 looks ridiculous - but it's not! In fact my first thought was you misquoted Burgess. Showing my age, I guess.
4...Bxc3 5.dxc3 is a tempo up on what black wants in a Rossolimo Sicilian, except...
5...Nxe4!? 6.Qg4 Nf6 7.Qxg7 Rg8 8.Qh6 d6 9.Bg2 Nc6 10.Nf3 Rg6 11.Qe3 Be6 12.b3 it was still roughly equal up to here
12...Qd7? 13.Nh4 and the engine says black was lucky in Berkes - Timman, Gyorgy Marx Memorial 2010.
https://www.chessgames.com/perl/chessgame?gid=1587813 4...Bc5!? caught my eye. I'm not sure if it's a novelty, but it's not in the ChessBase database. However it transposes to a bunch of games, arising from ...e7-e6-e5 rather than ...Bf8-b4-c5. Whites have even played 5.Nf3 and 5.Nge2 in that position. Unfortunately, 5.Bg2 or 5.d3 or even 5.h3!? must be good.
Edited: Fritz says 4...Bc5 5.Nf3 Ng4 6.d4 exd4 7.Nxd4 Nxf2 8.Kxf2 Qf6+ 9.Ke3 Nc6 10.Ncb5 O-O 11.b4 Nxb4 12.Bb2 += , 10...Qe5 11.Kd3! +/- idea Bf4, and 10...a6 11.Nxc7+ Kd8 12.Nxa8 +-. So 4...Bc5 doesn't even qualify in the hope chess department.
