Some other modifications that could be made to the viola to make it more ukulele-like include:
* Adding a capo to the neck to shorten the strings and make them easier to play
* Using a different type of string with a lower tension to make the instrument easier to play
* Adjusting the bridge to change the intonation of the instrument
* Adding a pickup to the instrument so that it can be amplified
Once these modifications have been made, it is possible to play the viola like a ukulele. However, it is important to note that the viola is a different instrument than the ukulele, and it will not sound exactly the same.
