It's not cheap but has anyone tried this and would it fit?

I wouldn't mind a bump on the cowl...

Default I have one installed

I have installed one and did modify my cowling, but no bump. See my post from earlier this year. The Cowl is longer and used a prop extender with a 3 blade. Also modified the mounting bracket lowering it so it would fit under the cowl.

I built my 12 as an EAB not a ELSA. I use the 40 amp as the primary and the Rotax Gen as the backup. They are controlled by the vertical power and manually turn on and off. If needed I flip to the Rotax Gen and can shed the load by turning off the 2nd EFIS and other equipment as needed.

Another alternative (Tho Expensive..!) SportairUSA have a rear bolt on Alternator that Piggy backs on the Original Eng Alt. & puts out 26 Amps looks like a list price of $3575 USD............also a souped up Rotax 912 engine!

This one bolts to the ROTAX where the vacuum pump would go. Might require going to a standard pitot. http://www.aircraftspruce.com/catalo...alternator.php. Integrating the two would be interesting. Note there is a thread about this. See http://www.vansairforce.com/communit...ad.php?t=80077. And note what a CTLS powers with the standard setup.

Default 2nd Alternator Required???

With the future installation of ADS-B equipment into the RV-12 cockpit, will the standard single alternator output continue to handle the additional load requirements and remain within operating limits, or will a second alternator be required?

No one but vans has the load calcs in detail. But go to this thread and check the links from it. http://www.vansairforce.com/communit...ad.php?t=80077. There is an EAB with dual Skyview in the UK with no problems. The CTLS is dual Skyview plus lights plus other stuff including electric flaps on the standard system. The RV12 Skyview mod electrical distribution avionics connector box comes standard with the option for plugging in a Garmin 496 or similar and an ADSB box in addition to that. I am not worried at all about adding an ADSB box and intend to. There is a thread about a wiring mod to measure the actual output being used in flight -which would be really interesting - but I don't think anyone has done that.

Dynon has stated the ADS-B box will draw 0.2A
