Does this make sense?

Ram is – currently – one of the last remaining focused brands in that it only sells a certain type of vehicle; i.e., pick-ups. The same used to be true of brands such as Porsche, which used to sell only two-door sports cars. It now sells SUVs, too – and that has worked out very well for Porsche. Maybe it will for Ram also.

On the other hand, it may not work out well for Jeep and Dodge, which already sell Stellantis SUVs.

The SUV Ram intends to sell will almost certainly be a variant of (or closely related to) SUVs sold by those other Stellantis brands. In other word, Ram's SUV will compete for resources and customers with other SUVs sold by other divisions of the same corporate entity (Stellantis). This is a problem Porsche does not have. Though Porsche is a part of the VW combine, VW does not sell slightly different variants of Porsches – and Porsche does not sell upmarket VWs.

Some point out that, back in the day, there was a Ramcharger, which was kind of a Dodge variant of the OJ Simpson Ford Bronco. It was basically a truck with two doors and a camper cover over the bed, from the factory. It was cool. But – in those days – Dodge sold trucks and there was no Ram. The latter became a separate division in 2009. Dodge stopped selling trucks after that.
