Placing the SD2IEC inside a 1531 datasette empty shell could an option although it's a large rig.
I'd prefer, however, an external 5 VDC power source. The datasette is controlled by the 7501/8501. The CPU gets really warm when operating the datasette. Not to forget that all I/O ops go via the 7501/8501. Replacements for blown CPU chips are really rare.
Another chance would be to take the power supply directly from the Plus/4 PSU infeed, right beyond the voltage stabilizer. That's an L7805, isn't it? Can't remember now since I haven't looked inside my machine for years.
