My ha'pence worth from my world of bodging. Yes you can use a threaded steerer with an AHeadset. Problem though is often finding a threaded steerer with enough length to use as AHeadset is intended. You can however combine the two headset types as I will explain. Get as long a threaded steerer as you can get so you say would need to chuck in a few spacers beneath the locknut. Get hold of a 28.6mm seat clamp as narrow as you can find (presupposing you are using 28.6mm steererd forks). File flat the lip that these clamps have to stop them sliding down the seat tube. You now have a steerer spacer you can lock down. Assemble the forks in the AHeadset, place spacers including new bodge lockable spacer beneath the locknut and wind down the locknut to tension the steerer into head set then lock down the bodge spacer. The bodge spacer acts like the stem clamp of conventional AHeadset set up. Then fit quil type stem as normal. Whole set up is as secure as AHeadset yet you can still fit a quil stem. Admittedly its a bodge and require a bit of trial and error but I find it works a treat 
Point to note though, an AHeadset wedge spacer made of plastic can deform and inbed itself in the threaded steerers threads making removal painfully difficult and often destructive. AHeadsets with metal wedges are better as they tend not to inbed.
