Can the heads-up notification height be increased to 256dp?

Question

I see that setting bigContentView increases the notification height to 256dp but this applies to only notification in expanded form.
Can the heads-up notification itself be made of the size of bigContentView? Using headsUpContentView only increases the heads-up notification size to medium format of 128dp.
I need large-format version of heads-up Notification.

Answer 1

No, all notifications will be uniform in height until the user opts to expand them or they are promoted to the top of the notification list.
