No I don't think it is an awful idea. It can be done. These are 30% larger seeds than CIR & even larger than some other varieties. Larger seeds will not incorporate into the soil as well as a very small seed. So I would frost seed it a little earlier. Say February as opposed to March. Or right before a snowfall.
If area is prepped you could even dormant seed it now. Broadcast and cultipack before ground freezes.
As for other considerations, it's going to germinate quicker that we all were use to. So be careful with spring burn down. If prepped I'd just spray your pre (simizone or atrazine) right before green up. From there normal switchgrass establishment practices .
