iPad Can the Keyboard font be changed?

Nope not possible. Use a different keyboard instead.

 

Check out the main 3rd party keyboard topic. I really like Swype (which had various iOS9 updates already but didn't help) and also used Path Input for iPad but both apps are much slower (especially Path Input) to show their keyboards in comparison to Apple keyboard since iOS9 and still in iOS9.1 on my iPad mini2. This wasn't the case in iOS8.3 and 8.4 so I think that there is something wrong with the 3rd party SDK in iOS9 that need fixing.

The ones that have swiping and can work without full access are:
Swype - other languages other then English need temporary full access for download (can be turned off after download)
Path Input | Path Input for iPad | Path Input+ (iPhone and iPad) (unfortunately haven't been updated since quite a while)
Nintype
TouchPal - unfortunately needs full access if your language is other then English

I would really wish that Apple would come up with a swiping feature in their own keyboard.

 

It would be really cool if google could bring their keyboard to iOS. I loved the UI and the swype built in.
