A 5 minute Lezghinka would be insanity.
Of the three listed I would choose the 2nd one because I would like to hear Raum played (who I haven't heard played in concert before) and the Lyapunov is a rare treat too and fantastic to end the 1st half I think.For the 2nd half I wouldn't finish with something that is too long because at the end most people might be exhausted. Perhaps end the concert also with a few 5-6 min piece? Maybe a Debussy Etude/Prelude or something from Ravel? And for some reason Islamey maybe that will mix logically well with the Lyapunov?
A 5 minute Lezghinka would be insanity. Good choice though!
I wouldn't play 2 piano sonatas and a whole suite in the same recital...
