You'd have been better putting this question in the 16mm forum.
Super 16 was originally developed for blowing up to 35mm, so there are no problems in that respect.
If you do a search in the forum you'll find lots of threads discussing optical optical or DI blow ups to 35mm. You should discuss with your lab how they handle the blow up workflow and the costs.
Here are a couple of threads:http://www.cinematog...amp;hl=Super 16http://www.cinematog...amp;hl=Super 16
Down side to Super 16 is you can't project the format with sound.
Regular 16mm lenses may not cover the Super 16 frame.
For a quality blow up you need a high quality lab.
