Shift work can wreck havoc on our cycadian rhythm which can trigger BP. Double shifts will certainly mess with you. However, we all react differently. You may be fine getting through the odd Double Shift but be watchful for symptoms. You don't want to have a breakdown/episode and have to stop work altogether.

how are you handling the shifts/double shifts? If you are ok then the odd double would be fine just be careful. Money is not worth your health.
