i don't think you would have any problem enlarging any film to that size.
you can probably increase your iso even higher by hypering it in h2o2

it isn't hard to enlarge anything after it has been electrified,
i have some 8mm film stills for sale in a gallery and they are as big or bigger than you asked about ...
swiss lenses make a difference, not that cheap german glass
