Is it possible to run both relay setups on a single system consisting of 2 svc subs and a single 2 channel amp?

The two setups are shown in the relay section of this site. One is for stereo to bridged switched outputs and the other is for switching from series to parallel and back.

Does anyone know how to do this if it is possible???

You may need to use more relays wired a little different to switch from parallel to series, while in mono only obviously, to do it with just 2 SVC subs (2 voice coils). If you had two DVC subs, you would have to wire one of the "Stereo to Mono" configurations from the amplifier to two of the "Series to Parallel" configurations to the subs, one for each DVC sub. If I can find some time this evening, I'll draw diagrams of both configurations and add them to the site and post a link here.

Here's the relay set up for 4 woofers or 2 DVC woofers to change from stereo to mono and from series to parallel. Switch A (-) is to switch between series and parallel. Switch B (-) is to switch between stereo and mono. With both switches off, the amp is wired in stereo and the woofers are wired in series. *If your amplifier configuration for stereo and mono are different than shown, this obviously will not work. I'll draw the other diagram tonight if I have time, no promises though ;).

I started on it already, but haven't had the time to complete it. I'll try to knock it out this evening, but no promises. When I do finish it, I'll post it here.
