No, you can't do this.
As already mentioned, different species simply cannot interbreed this way.
You can't cross a tobacco plant with a tomato, you can't cross a monkey with a dog, and you can't cross a cannabis plant with a strawberry.
With respect to hops, that plant is distantly related to cannabis, but its nowhere near close enough that a simple cross is possible.
I've been told its possible to GRAFT a cannabis plant onto a hops vine, or vice versa.
Now, I don't know if this is true, but even if it were, you'd basically just be creating a "frankenstein" plant that was part hops, part cannabis. The cannabis part of it would still look, smell, and behave the same as any other cannabis plant, so you wouldn't fool anyone, and you wouldn't end up with THC-laden hops flowers.
With respect to what you might term genetic engineering, yes it is possible to transfer individual genes from one species to another.
Some of this kind of work has been done with tobacco plants, I think, and for obvious reasons, a tobacco plant might be a good candidate to transfer THC production genes.
The problem is that doing this sort of work is highly technical, complicated and quite expensive.
With respect to THC production, that's not going to be one gene to transfer but rather a whole complex set of them, involving synthesis proteins, transport proteins, regulatory proteins, etc. I'm pretty sure that these particular enzymes and regulatory mechanisms for cannabinoid production haven't even been worked out yet. Even assuming they were, transfering them wholesale from one species to another in a functional way would provide an unprecedented technical challenge. For example, who is to say that THC production wouldn't simply gum up and kill a tobacco plant?
So far as I know, nobody has ever accomplished anything remotely close to that before. I wouldn't say its "impossible" but at the present time its effectively science fiction.
If you want to continue with these sorts of pipe dreams, I have two alternative ways to go.
a. Find *another* plant that produces THC like molecules, and then genetically engineer and/or selectively breed it to create cannabinoids. Unfortunately, humans being what they are, I'd imagine that if any other such plant existed, that would be well known already.
b. Selectively breed and/or genetically engineer an actual cannabis plant to the point where it no longer physically resembled one. Again, this would pose a massive technical challenge, though I think this particular angle of attack would be quite a bit easier than say trying to cross a hemp plant with a blueberry!
