I was about to say hold up plenty of 1/8 chainrings out there but then decided let me make sure that the crank isn't something French like 50.4 and of course it is 50.4. You should be fine with a 1/8 chain on 3/32 parts you just cannot do the opposite if I am remembering correctly.

However you might consider getting a different crank with a 144 BCD so you can run standard track chainrings and find loads of options very easily. I am sure in the C&V section or elsewhere on the internet tubes you can find someone who wants a Stronglight crankset or there might be an adapter out there still. I believe SunXCD made one that could at least get you to 130bcd and you have loads of options. You can also just continue as normal but having more choices is kind of nice. I have an old Campy 116 bcd crank that I was going to use on a 1x build and I am thanking myself I didn't and found a nice Tiagra HTII crank so I can find more chainring options and easy install.
