That's all fine, there's no prohibition that I'm aware of. It just may be worth checking into the cause of the excess file size, since in most cases it should be possible to fit an official model as an attachment within the current limits.
In the model there are 19 pieces with stickers, in 8bit PNG format, which weigh only 2.5 MB.
The model without stickers weighs 8MB
The count doesn't add up!
the integration of the stickers, is calculated incorrectly in the final .io file.
