The C11B uses the 52D66 gyro with just a roll pick-off. The Century 111 uses the 52D67 with pitch and roll pick-offs. None of the Garmin gyro emulators – GAD43/e (G500/Txi), GAD29b (G5) or the new GI275 can be used to replace these old gyros.
Sigmatek make direct replacement 5000E gyros with attitude pick-offs for those with old/broken Century units. This could be installed in the turn co-ordinator location if a glass primary display is desired.
KI256 / KG258?
This may not be the desired answer but I’ve been flying behind vac pumps and KI256s for 18 years and it really isn’t a big fish to fry. I’ve never had a vac pump fail (I change them as soon as the vacuum falls below the green arc) and I have a spare KI256 and change then over. They come up on US Ebay rgularly and cheaply.
I would spend money on a more flashy navigator (IFD or GTN), TAS…

What is the current attitude source for the Century AP?The vacuum-driven AI.

Given time, perhaps the AV-30 will fill a void, or, just maybe, Dynon (but at a much higher cost, and possibly not in EASA planes).
But seriously, price out an Aspen E5, it recently got a nice software upgrade and does a real HSI representation.
ah this really sucks.
That’s why you want to get rid of the vacuum system…

Back to Aspen I guess… Not that bad of an idea…
