Naw man, get in over your head that's the best way to learn to control them. I would probably skip the Tikal with your space unless you flower it from seed. The Malawi should do well, I'd ask ACE in an email to send you the New Malawi Killer seeds. Those will be nice and tame, the Old Malawi Killer is wild. Panama can be done, Congo would be another. Anything with Nepal Jam would be a good choice too.
The other challenge of running different strains which you are seeing now is the different heights of the plants in relation to the light. That's why having multiple smaller lights would work best so you can raise and lower as needed.
