Taking a solo on Bass, and a Bass playing a tune are two different animals for me.
Plenty of examples of nice fretless or Upright players taking/playing a lyrical tune over some sensitive backing,
You don't have to be a technical genius to do that, but have a good ear for melodic phrasing.
Its the player that gets a Bass solo a bad name, not knowing how to construct and build a solo,
but just flying around modes and scales without really getting from A to B with any meaningful melodic or rhythmic context.
So if you are confident in doing it, why not ?
