99% sure you can buy the QR lever separately for your existing clamp. Check some of the big online shops that do Hope stuff.
[s]I don't think so as the recess for the brass bushing is not milled out on the non-QR version?[/s] I stand corrected - That was the old ones:
Hope seat clamp QR conversion kit
Converts 2009 onwards bolted seat clamps to QR type

It's like the one in your picture you posted, so I'm assuming that will work.
Yes it will, you just need to buy the kit that foxyrider mentioned.
EDIT: my first post should have read 'if it's like the one in YOUR first pic it won't work'
sorry for any confusion.
The one on UKBikeStore is Quick Release to Bolt on. Not the other way around, and I can't find any other dealers.
Get in touch with Hope. They've been excellent with advice when I've emailed them.
You can convert a new style bolt-up to QR, I had to do it after the threaded insert in my brand new one snapped while tightening up the bolt!
The QR fits just fine and dandy, the threaded insert is stupidly thin walled. Don't know why they have to make it out if soft as $h!te alloy
