Yeah well you just need to find the right sponsor! I think the main issue will be that you’d have to wait some 90 minutes for a few minutes of connection! 
I actually asked Bart about that recently. They used a more expensive industrial version of the Rockbloc module and seemingly didn’t have many issues with it. They’re also after a Mozzie atm.
In general I’m not really a fan of satellites for cost/performance. A better option would be a high altitude solar powered persistent drone running Arduplane using mulit-gigabit microwave link…in fact if you do it right like SHARP you could use the microwave energy through a rectenna to power the plane as well! To get around the regs you go out 12NM from the coast until you hit international airspace, which means you can fly up to whatever altitude you like and stay there for however long you want. According to GE you still get LOS comms to Dalby from there…The only thing is it will need to offer a public AP otherwise it would be in trouble with the challenge rules!

Do you know the longest Arduplane has ever flown? I think PX4 done 81hours once with their solar plane? I’ve been meaning to build my solar X8 for a while now.
