Yes, this will work basically.
The only problem that might arise with this special setting, is that the TS outputs have a very high volume, when the Kemper Power Kabinet is driven to high wattage in "Kone mode". This would potentially overdrive your pedals and create unwanted distortion.
In that case I might just get the fender fr12 since I have to run the wet effects post since there isn’t a fx loop in the player.
