The requirement it to have a magnetic heading reference. As such, the SkyView of course qualifies. Then however you have to deal with whomever is going to sign off the plane. I had my RV-10 done by the FAA FSDO office and before they showed up they sent me a list of "must haves". In addition to a transponder pitot static check, I had to have a TSO wet compass. Bottom line, ask the FSDO/DAR what he/she wants. If they want a wet compass don't argue the point, just put it in. BTW - the SIRS Compass that Van's carries is a real nice unit. I even looked at it once to see if it was indicating correctly.
