Perhaps in the future there will be Accelerator PCIe card/Co-processor card based on PA SEMI Pwrficient SOC for running AmigaOS 4/AROS/Linux PowerPC/BSD PowerPC/MacOnLinux.
The card will be based on Slotserver or similar technology.

Perhaps a card with dual bus design with jumper (PCIe or Zorro), similar to IRMA convertible:
