The ZM could be the ticket. I have an S2 Custom 22 Semi-hollow and it definitely has a warmer tone than any of my solid body guitars. Barring the ZM, I'd say have a look at the SE Custom 22 Semi-Hollow or one of the SE 594 Singlecut Standards. An all 'hog' guitar definitely won't be as bright sounding as a maple capped guitar.
With regard to noise on the semi-hollow, I don't have any major issues with excess noise. I play mine in my living room in my condo pretty close to the FRFR monitor and don't have any major issues, even with high gain patches on my Helix (i.e. models based on the Dual Rectifier, Rockerverb, BE100, Archon, and 5150). Just use a noise gate and you're golden.
