[Problem] CPU Upgrade of Acer Aspire R7-572G

Hi, I have had this wish to bring the R7-572G to the most up-to-date it can be for a while (nostalgic reasons :D), and now bought a second used one to experiment on. There seem to be a shop on taobao willing to perform the BGA CPU replacement too.

I’m thinking of replacing the i5-4210U with a Broadwell i7-5650U.
Read that Broadwell will have a bit better power consumption than Haswell, also want to see if I can have 4k60 output capability over the miniDP by upgrading the CPU.

A few questions for the process:

  1. Does this sound possible overall?
  2. What in the BIOS will likely prevent the computer from booting up/need replacing? Or could it just boot afterwards, but just that ME turns the computer off after 30 min?
    a. Intel Management Engine firmware?
    b. Processor Microcode?
    c. iGPU VBIOS & GopDriver?
  3. Seems like 5650U is mostly used in Apple MacBook Air. Will the VBIOS and GopDriver extracted say from Aspire E5-573G or from this post likely support the HD6000 iGPU in the chip? Or is it more likely to work if I use a more “regular” chip like 5600U or 5500U that have HD5500?
  4. In search of a “donor” bios to supply the modules I may need, I see Acer Aspire E5-537G has a i7-5500U CPU. Will its BIOS likely have support for all Broadwell ULP CPUs, or only a select few CPUs?

Also a few curiosity questions for the CPU itself:

  1. Is the chipset integrated onto the CPU substrate? Which chipset is that? (I don’t seem to find another chipset-looking IC on the motherboard, but see 2 dies on the CPU substrate)
  2. Would using a 28W TDP CPU (4578U/5557U) in a system that originally uses 15W TDP CPU likely cause issues?

For reference BIOS image of the computer, I’ve done a advanced menu unlock a long time ago and posted image here
