Mudguard for 26" mtb

Looking for a front mudguard for my daughter's new bike. It's 26" with a suntour air fork. Clearance is quite tight already, I'll probably pop some tubeless tyres on at some point which could make it even tighter. 

Any recommendations for a decent mudguard? I'd like something like I've got on mine, the RRP proguard, but I'm not sure there's room for anything like that. Mucknutz alternative looks possible. A little enduroguard style flap of plastic will fit, bit I'd prefer to go with a longer length guard if possible.

Anyone got anything already set up on a 26er?
