For Wind-up Alexander, you could try unsyncing it yourself or posting an unsync PF. It also drops in Savage so you could do it under the guise of a mount farm since they're both guaranteed drops.

For Calofisteri, it might be harder to get an unsync party for. Dunno how many ppl you'd need to clear it, but you might only need one or two ppl per alliance. This one might be better to just queue up for in DF.
