Answer To Your Question
Yes and no....

Yes: You can make a UI how ever you want for aslong as you can design it.
No: Eventually drawing enough huds will cause a few issues for you.

[Tip: If you want a nice looking circle that isn't pixelated, Draw about 11 circles 10 to make the outer shape of the circle and 1 to enclose the circle[Sub Issue with this: There is no 100% That you can get it 100% Perfect without hours of working on it.]]

Huds & strings both count as huds and if you draw too much as for example 11 circles + strings you'll eventually get on the limit and you won't be able to spawn anymore shits.
Deleting game huds already created will save you a few space but not a lots.

Yeah that's why i put the No: Eventually drawing enough huds will cause a few issues for you.

but after that you put
