It depends how old the bushes are: if one or two years, you can dig out most of their roots and they will settle in fast. Worth a try whatever.
Tunnels just need time and patience, while the plastic would be difficult to dig out and then free up from around the door frames, without losing any there and finding that you had not quite enough to re-secure it when reassembling. Not impossible though. If more than three or four years old, the plastic is not worth saving for recladding.
