Clipless pedals and a good shoes help make this better.
With modern compact drive chainsets, swapping to a larger outer ring can lead to issues when changing up from the middle ring to the outer ring. Shimano used to allow a twelve tooth difference, but we always used to be able to bodge something (she says while running an old Suntour XC Pro MD chainset with eight speed Shimano XT cassette and 9 speed deraileurs, all worked by seven speed thumb shifters). However with compact drive the front deraileur has a smaller throw and shorter cage.
A 42 front to 11 tooth rear sprocket should give you a fairly good gear. If you are running disk brakes you can swap the rims for 700c road bike rims and narrow tyres which improves speed a little.
Spinning is your answer though or finding a Touring bike set up that you can put on the bike, which will give you 28-38-50 tooth chainset and deraileur. A high cadence though is far better for your knees than a big chainring.
