is it OK to use multiple blades of a feeler gauge to measure a larger gap

Question

This feels like a bit of a silly question because I don't see any reason why it won't work fine - but I wanted to get some experienced/pro feedback. I need to measure a gap of .035 inches, my feeler gauge ranges up to .025 .  My plan is to measure the gap by extending both the 0.025 and 0.010 blades and pressing them together with my fingers, then measuring as usual.
Can I expect this to yield an accurate measurement? and is this a "correct" or "normal" way to use a feeler gauge?

Works as long as they are clean.
What is the tolerance on the gap you are working with? Compare that to the error of putting two feeler gauges together - check with a micrometer or vernier preferably a good one.
