Smaller than Brahmos-1 because it will use lesser fuel to achieve same range but since scramjet generates far higher Isp than ramjet it needs less fuel to achieve same range ?
Can a scramjet variant of Brahmos II can do the same type of trajectory as ramjet Brahmos-1 ?

There are many unknowns to fathom the envelop of Brahmos-II, only when there is clearer definition on those can one hazard guesstimate.
To begin with if the range of Hypersonic Brahmos-II is limited to 290 km, then hypersonic engine etc will not make sense (because hypersonic flight need to be at much higher cruise altitude for engine and range efficiency).
Now if the range is different, then small is relative term compared to other (non-Brahmos) missiles of similar capability (E.g. hypersonic Shourya)
IIRC DRDO hypersonic engine is based on Kerosene, so fuel ISP is no different from Brahmos-1 ram-jet, its the engine efficiency and cruising altitude that will determine ISP and range capability.
