You're going to have to get a new chain to suit whatever cassette you get, so the question is will the new chain fit on your front chainrings ok. The answer is "probably", but hard to be sure.
On a 5 speed, the rear spacing on your frame is probably 120mm. To go up to 7 speed, you'll have to spread it to 126, to go up to 8 speed or above, you'll have to spread to 130. This should be ok on a steel frame, but spreading a full cm may take more force than you want to do by hand every time you take you wheel on or off. May want to get the frame cold set by a shop.
Next question is if you have a 27" wheel or 700. There are not a lot of 27" inch wheels with a cassette hub, but you may be able to find something. As 1FJEF notes, you can switch between 27 and 700, but there are some considerations to check first.
The big question is - what are you trying to achieve? More gear choices, stronger axle, just a cooler looking new wheel?
