AD8099 ADA4899-1... mux them together

Hello,

I'm using 2 AD8099 (G=20) and 2 ADA4899-1 (G=1), all four are muxed to drive a AD8331...

The circuit should be very low noise and the Bandwidth around 30MHz.

I'm wondering how many others AD8099 can I add, without degrading performance?

I would need to have 6 op-amp muxed...

Does the crosstalk will become an issue?

I didn't put the circuit in Spice, do you think it worth, and will it allow to see where the limitations are?

 

Many thanks for your help!
