Question: sigma ef-530 DG super HSS with YUONHUO radio wireless?

I have a Sony A100 and a Canon Rebel, I would like to purchase this flash with the canon hotshoe and use it in the sony camera with a hotshoe adapter, will it work? or I will lose some of the functions? (with a hotshoe seagull adapter for example)
I am also using the radio wireless transmitters (Yuonhuo?) with vivitar 285HV flashes. Can I use the Sigma flash in High Speed Sync with my wireless transmitter? or will only work at high speed if I use it as a slave?
Thanks in advance for the answer,
(I am looking for the best flash option to make High speed sync affordable)
