If you just want to use Waves Plugins along your TF5, then another alternative could be a desktop PC with a PCIe Dante card and Superrack Performer. Also available as a ready-to-go solution from Waves: SuperRack LiveBox - Mix live with any VST3 plugins - Waves Audio . But you would not get a Soundgrid net then.
An alternative to the Hear Technologies WSG Bridge mentioned by @Adi.Waves is an idea from @houghton.cb : a Digico Orangebox with a Dante card and a Waves card (see also this thread: LV1 Soundgrid and MADI & DANTE Options ).
A company called http://directout.eu also builds boxes which can be fitted with Dante and SG cards.
