I would for sure give it a chance.
My EB runs with your Modpack for Rome.exe, CityMod 5.1 and Ferromancers EB for BI.
It's nearly stable at the moment (Qart'Hadastim campaign, 229 BC; only 2 CTD's after battles so far, maybe they were caused by saving directly before the battle), but a complete "all-in-one"-Installation would be quite cool.
And I don't have any intention to change to Alex.exe (mainly because I don't have it... ).

Oh, before I forget again to mention: I really like your Modpack.
