Roundhouse question

I have room for 12-stalls-worth of Walthers roundhouse. Rather than having all of the same “type” of roundhouse (kit #933-3041), I was thinking of making the last 3 of the stalls kit #933-2900/2901.

I have seen this type of thing prototypically, having a newer roundhouse section added to an existing older roundhouse, but I was wondering if anyone has modeled it on a layout yet. And if so, do you have any pictures?

Thanks.
