Undrilled discs.

Maybe you could custom order hubs with the desired bolt pattern from here, I am sure you could find rotors in that pattern and size.

That sounds like a dang complicated process especially if your back rotors are stock.

I can't see how you are going to make new rotors work if the Halibrands are true knock offs? Where's the center hub for the wheel coming from?

IMO the best option is probably a bolt on hub converter the likes of which Vinatge Wheels sell. See here at Vintage Wheels They sell a 5 x 4.5 bolt pattern, but normally for a more modern 5 pin knock off wheel, but they will do 6 pin hubs to order. These bolt on to you oem wheel studs and then have pins to locate wheels with the center spinners (or lareg nut if you prefer).

Next thing is check the amount the hub pushes the wheel out in the fender and wheel offsets etc.

They make an adapter to bolt onto the 5 stud pattern to the 6 pin with a knock off ... not thats I agree or this is my taste ..but it is made by some wheel company that makes GT40 style and cobra halibrand style wheel.

FWIW, I've had some luck in welding up hub holes, machining the welds flat, then redrilling to other bolt patterns. The hubs are forgings so they gas-weld OK. Note that if you do this, you'll need TWO different spares- or forget about carrying one at all.
I've also had luck in TIG-welding holes in aluminum wheels shut and re-drilling. This is a little more complicated. And of course, the quality of the above welds are a limitation, so pick a good welder.
