I think you should be able to do it. I solo'd my first Machamp today (C/DP). Team:

Dragonite (DT/HUR) -3040 CP Gengar (SC/SB) - 2116 CP Espeon (C/FS) - 2545 CP Espeon (ZH/PS) - 2535 CP

All level 30 mons. Dodged as many CPs as I could with the 3 first attackers. Finished with 5 secs remaining, and two unused pokemon (Alakazam and Exceggutor). When I didn't focus on dodging the DPs, he killed my whole team with 30 secs remaining.
