10 day travel itinerary advice, help needed!

Hi everyone!

I booked the flights and will be in Uzbekistan in September for 10 full days.

What would be an ideal itinerary to see everything? I was thinking of visiting Tashkent, Samarkand with a day trip to Seven Lakes, and Bukhara. Khiva seems logistically hard to get to. Would it be a mistake not visiting Khiva?

Thank you. Every help is appreciated :)
