Hello everyone

I'm trying to update my Aspire Model NO: V5WE2 (E1-572) as the title says.
Current specs:
i5-4200U
2x4GB of DDR3L (MAX)
256GB SSD
Problems:
HDMI port not working
A strange vertical line appears in the center of the screen when it moves
Running a bit hot under load (it must be cleaned with the following application of thermal paste)
General low battery life
Having said that, to solve these small problems and then try to maximize the specs I was thinking of buying the following pieces:

Anyway upgrading to i7-4510U to solve the problem of the HDMI port and to maximize the processor (and also get 16GB of ram that is the max supported). Comparing the shapes of the current motherboard (with i5-4200U) with those of this new one shouldn't be a problem.

Finally, a whim rather than a problem: it is possible to replace the standard keyboard with a backlit one? Are there also problems with the components I have indicated? It is not a substantial expense but I would like to proceed calmly with the purchase.
Thanks in advance to everyone for any answers, good evening
