Can I use a ATX12VO Motherboard with a Lenovo PSU with 14-pin connector?

I have an old Lenovo ThinkServer TS440 that has a PSU with a proprietary connections, which is a 4-pin cpu connector and a 14-pin motherboard connector. I was thinking I would have to replace the PSU when I swap put the motherboard for a modern Intel system, but it seems that MSI plans to commit to ATX12VO power in, which uses a 10-pin connector instead of a 24-pin connector. I'm looking at the pinouts of the Lenovo PSU and the ATX12VO spec and it seems like i should be able to make an adapter that works...
the Lenovo 14-pin connector
the ATX12VO connector
it seems I can make a short adapter that removes the -12 and +5 wires and splits one of the +12 wires and merges two grounds...
it does have a 4-pin CPU header, but making that an 8-pin cpu header seems easy enough

1. Keep in mind that adequate wattage/amperage is just as important as the voltage.
2. The PSU is one of the most important parts of a computer build.
3. Just because it may be possible to do something, doesn't mean you should.

And last but not least.... Just... NO !!!!!

I'll echo Ghot here:

Very, very, very bad idea. Do not mess with your power supply.

I would just get some extra connections and make patch cables, those are common enough
