This is a good point. There are plusses and minuses to giving a "weenie" facade to an e-ticket.
The plus is that, for the many of the "general public" casual guests who wander through the parks without plans or even looking at a map, "weenie" facades will make them visit the must-see attractions. This makes a big difference in terms of guest experience.
Out of curiosity about this very topic, when people mention that they've visited Disneyland, I've often asked what they rode, and a surprising number of them completely miss Indiana Jones Adventure. If you care about the experience of the average guest, this is a big problem.
The minus is that - as
@MansionButler84 and others above have said - there is a lot of value in being surprised by the scale and grandeur being far beyond what one would expect from the outside. So, having at least SOME e-tickets without mega-"weenie" facades could add to the guest experience. But I think even those can strike a balance: The Haunted Mansion at Disneyland is a good example, where practically every wandering-general-public visitor rides it because the building draws you in, but at the same time the facade doesn't actually give you a sense of the attraction's true scale.
The Rise of the Resistance entrance should probably have balanced this better in a simple way: Just make the turrets 50%-100% larger! They'd still look like a "temporary" structure hidden in the forest, and they still wouldn't reveal the true scale of the attraction, but guests will nevertheless be drawn towards them. (Hopefully, the way they stand out against their surroundings, and the way that the main guest flow passes by them, will be sufficient to entice most wandering-general-public visitors - but we shall see.)
