My understanding (and experience?) is quite different from Jan's.
You can mix StackWise and StackWisePlus technologies (I've done it) but you'll lose StackWisePlus enhancements.
You can mix features sets (I've done it). However, if you're using advanced features, found on one switch, and it fails, you lose those features across the stack. (So, it's a good idea to have at least two stack members with "better" feature set, for redundancy.)
You can also mix IOS versions, but dissimilar versions must support the same StackWise version. Easiest way to insure this, run the same IOS version on all switches.
One last gotcha, which doesn't appear to apply to you, the 3750G-12S has additional SDM templates, unique to that model. If you stack it with other models, you need to use one of the common SDM templates.
Overlooked another gotcha, 3750X, running LANBASE, won't stack with others.
I agree with Joseph. You can mix-stack 3750/G/E/X together but your stack ring speed will depend entirely on the lowest-common-denominator.
Next, to answer your question, no. You cannot stack the two switches together because they are both running different IOS versions. There's is also a possibility that, in event of a failure, your stack may fail because the 3750E/X may NOT be running IP Services feature set.
For your stack to work, make sure all members of the stack have the same IOS version as well as the same feature set.
In case you're wondering, yes I have a few stacks that are a combination of 3750/G with either 3750E or 3750X and they work but running at a lower stack ring speed.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
