I have been reviewing many available forms of sword styles and the only real issue is one if avoiding any contact with the blade.
In many of the relevant flashy sword forms within WuShu, the overall look is spot on IMO but there is lots of push blade, incidental body/arm/sword contact, and other related touches that would need to be removed for use as a light saber form.
There are arguments that a rel light saber would not behave like an actual sword...but as we only have these prop proxies then we work with what we have

Any decent sword form that fits your vision of movement will look great IMO.
The trick is picking one that appeals to you so you will be able to best use the established movements to their fullest value.
Here is a good Wushu technique that can be used for sabering...flashy and fairly easy to learn (though go slow, limber up, and be prepared for wrist pain at first...this one is called 5 flower but there are dozens of flower forms
Practice this technique and apply it in moderation...say after a clash of sabers when y'all step apart and then a few flower spins and ready again...
