I would say its match up dependent, but generally I can't see it doing very well. Main problems I see are first being that your battle plan is to try and keep 6 ravagers surrounding 1 archon, makes you susceptible to melee and DS not to mention LOS issues. If you bubble wrap with all the warriors which is clearly your intention, most of those warriors will never be in range to rapid fire. Second major issue is morale, sure obsidian rose has a strategem, but with 7 CP and 6 blobs you will be out of CP by the end of turn 2 and thats an optimistic scenario. Your warriors are just t3 5+ 6+++ dudes, they are only a bit more survivable than cultists, so on foot they are gonna drop quick leading to those morale tests. A good opponent well know it too, and only shoot out 9-10 on each squad, which at 2k points its very feasible they could do this to almost every squad on turn 1. Once your bubble wrap is down those ravagers are doomed. That's just my opinion though, who knows new codex could work and surprise me.
