Google account migration

I'm trying to split off gaming life from personal life using 2 Google accounts. Probably quitting several due to either boredom or time suck factor, but there are a few I want to keep active including GoH. Most discussions I see center on IOS-to-Android migration, but I'm assuming the same thing would hold true for Android-to-Android. Are my only 2 options to leave the account on personal Google or totally start over from scratch with gaming account? That would royally suck as I'm almost a year in with a bazillion L5 mods and around 30 toons max levelled to 85 with tons more unlocked. A couple of my other games, the devs would allow a one time move via request and I'm hoping there's at least a way to do that here. Thoughts? TIA
