What are you planning to use for a rear hub? 10-speed cassettes require a different hub and different dropout spacing than a 5-speed freewheel.
I have a bike that uses Suntour friction barcons and a Shimano 9-speed cassette. It shifts perfectly but does require a somewhat subtle touch. Since 10-speed spacing is quite similar to 9-speed spacing, I doubt you'd have any issues with cable pull requirements.
