almost certainly
maybe, but see below
power handling/max SPL levels, perhaps bass extension - with appropriate filtering on one of the drivers, mitigation of "baffle step" loss
Note that most of the Mark Audio drivers are 4 ohms nominal, so either series connection or biamping is recommended
Also, as mentioned elsewhere, there are several designs for dual driver enclosures (besides my current hobbyhorse the Castle /tower) which might possibly be better suited to your particular situation than a tall dual mouth BVR or Horn that would be stunning in a larger room (such as your folks' living/dining room
) .edit:
and be aware that it'll be difficult to find consensus on what might be right for you - hell most of us don't agree with ourselves for more than a few weeks (otherwise you'd see far fewer "my latest project" posts on these forums), and you've apparently got months before it's time to push the "go button"
fitting into the room and "working" for the average listening position(s) are not necessarily the same things - ignore that at your own risk

What filters will i need? I will also need some XO or something like that.
I will probably serie-connect them, it's most practical i think.
Can you link some other dual-driver enclosures (still horn or something like that)?
Yes, might be cool to try them on in the livingroom but my dad thinks that nothing can beat a pair of Olle Mirsch OM-61 from the late 70's/early 80's... Yes, they're good but not that good.

well, the BSC filter could be all the "XO" you'd need, it would be described as a 1.5way

well, on second thought, given your placement options, the front/rear facing bipoles designs (i.e. Metronomes, Jim Griffin offset, etc) wouldn't be practical
forgot these:

and surely a dual driver Pensil design has been conceived, if not yet published?

I'm clearly out of my element here, but that could complicate a simple BSC filter applied to one of the drivers.

well, that was mostly in jest - if he's helping with the construction, he might be interested in the sound - but don't discount the performance of a speaker system due to its vintage alone (many of us have a lot of equipment in our collections at would certainly qualify as classics / collectibles/ oddities) and many of them are better than you'd think

Baffle-step-filter or whatever it is named.
Also i need something to stop the drivers from going down to for an example sub-100hz since my subwoofer will take care of that.
Doesn't require the former.
If all you're aiming for is 100Hz (although a single sub. shouldn't really be used above ~70Hz as sound is increasingly directional above that), you might as well just build a small sealed box for the drivers. The will be little or no advantage to you building the Lotus cab., or anything large; they won't have much left to do.

What is recommended XO for Lotus speaker then? I guess it's different depending on if it's 1 or 2 drivers.
Perhaps a passive line-level crossover (PLLXO) would be something to try later?

Just a bit. True - it costs gain.
Rullknufs, you could use digital EQ to experiment with the bass cutoff. If you have a multichannel soundcard, that's perfect, but if you only have stereo out, you can assign one channel to the sub and then drive the fullranges with the other mono channel. And then you can EQ each channel separately until they fit well.
