Domke F803 or F804 for D700 + Rolleiflex

[m3love]

I'm looking to buy a bag that can fit my D700 with 50mm + another prime lens, and a Rolleiflex 3.5, or just my Rolleiflex and a Canonet QL-17. I have the Domke F5Xb and it works good for the Rollei and Canonet but it barely fits my D700, and I'd like to be able to carry the D700 with my TLR, plus it kind of looks like a purse because its so small. Does anyone have the F308 or 408 and can attest to the size or have any photos? Your help would be greatly appreciated.
