Last turn I named a vet immortal BCLG and another greekguy the Great. These units had not been previously named. (I know you wanted the eilte BCLG but it was already named and I don't think we should put ourselves in a position of having to tell the Galls we've renamed units.)
Concerning the proposed rushes:
I don't think we should rush the worker in Grenadopolis - it'll be done in two turns and since there are no shields towards it yet it would cost 8gps. We currently have 13 workers disposed as follows: 4 on the front lines (for building roads, chopping forests, etc.); 3 near Provobomb and Shilhanopolis (improving tiles); 3 near the Keep (hooking up silks); and 3 in the Deep South that are pretty much done down there if we don't want to clear jungle - so they can head north.
I also don't think we should rush the immortal in

. It'll be done in two turns. The trebuchets we're considering rushing wouldn't get in place for a while so we can let this immortal build normally.
I do think we should rush the trebuchets in Carpetbomb, Provolution and Fort Incendiary. The cost would be 264g leaving us with 374g. That would give us 7 trebs. If we attack Spite from the forest tile to it's west it will take the trebs three turns to reach the attack point. The trebs would build next turn (129), reach the redezvous point on turn 131 and the attack could commence on turn 132. In addition to the seven trebs we'd have 13 immortals and six or seven pikes. We could also raise an additional unit in Unabomb. The forest chop should be done next turn then we could rush another pike or treb or regular immortal cheap.
After the current units are produced we could start barracks but if our seige of Spite is successful and our stack relatively intact we should have an easy time of taking Malice and might want to continue on our present course instead of investing in barracks. If the force we bring to bear is sufficient to reduce the Galls cities we should seriously think about starting a market in

or Semtex. Then we also need settlers and workers.
Anyway, I think we should keep our stacks where they are this turn. We should move the pikes in the turn before the immortals and trebs. That way the pikes can fortify as the offensive units join them.
