patentability

more details are needed to properly answer this question.

Nevertheless, in principle, yes you can. It comes down to how "obvious" would it be to combine them, and whether or not the combination provides any advantage other than those provided by the two separate elements.

For instance. A radio plays musis, a skateboard moves you around. A skateboard with an integrated radio moves you around while playing music. Hardly surprising, difficult to patent.

On the other hand, a given glass in brittle but very light and porous to gas X. Another glass is sturdy but heavy, and also porous to gas X. Their combination is averaging the strength and weight (to be expected) but is surprisingly and unexpectedly not porous to gas X. This may be patentable.

Also, please note that different jurisdictions may have different "threshold levels" for how obvious a combination may be, so you may get different results in different countries.
