How heavy handed are you as a drummer? Are we forgetting that there is a 5 piece drum kit in that small space along with that 100 watt Marshall stack? That little combo is going to get smothered. Turning down the volume on a 100 watt guitar stack. The saturation and tone the he wants isn't always attainable at low volume so guitarists have a habit of turning up their gain a volume to achieve the tone they are looking for. That is why they make low powered tube amps for recording studios.
I play with a couple of guys in a similar situation but in a much bigger room. The guitarist uses a Peavey Classic 50 2 X 12 all tube combo. It' only 50 Watts and it's louder then hell. The drummer is a little heavy handed but will use Promark Hot Rods most of the time. I use my old Peavey Combo 115 with a TVX 2X10 extention cab and a Sansamp BDDI into the front end. I have 300 watts and more speaker surface are then the guitar amp and I'm adequate to hang in there.
I would get a bigger bass amp if I were you.
