Way to have madVR process before SVP?

I'm using SVP to interpolate up to 60fps, and MadVR to upscale low res content to 1080p, player is MPC-HCx64.  It works great, but I'd to use higher quality upscaling in madVR, but because it has to process at 60fps the GPU only has 16.67ms to upscale each frame, any longer and I get dropped frames obviously.  Yes I could just buy a faster GPU but that costs money and I'm happy with their gaming performance.

If I could somehow allow madVR to upscale the video first and then have SVP do its frame interpolation on the result it might allow me to use much higher quality upscale settings.  I know SVP would always 'see' a 1080p input and use more CPU resources but I can live with that.  Even on high settings with small vector grids (on native 1080p content) SVP runs fine on my OCed 3770K.

Is there a way to do this?
