If the speakers are a difficult load, a solid state amp may be more unstable than the tube amp (depending on design of course)
Some things to consider - how loud do you need your speakers to play. How big is the room. What type of music are you listening to.
All these will determine if the tube amp in question can drive them.
If your tube amp is a good design, stability is not an issue, just because the speakers are low efficiency. If you're worried about back EMF, that's not an issue either with good iron, and not a result of low efficiency. What your refering to is damping factor. Feedback amps will have a better damping factor, than non feedback amps, and solid state are better yet. However it really has no relation on how stable the amp is.
I say build it, if it's a good design it will work.
