You should ask the Head Ref's is view on this. At the Greater Pittsburgh Regional, utilizing the chute door to manipulate a tote was viewed as a form of propping open a chute door with an object, and called as G6-1.

Relevant Q&As

Q260
Q.This question touches on Q164 and the recent update to rule G6. Can a HUMAN PLAYER use the CHUTE DOOR to contact and intentionally slow down or manipulate the movement of a TOTE that is in the TOTE CHUTE if the HUMAN PLAYER is only directly contacting the CHUTE DOOR? The update to G6 seems to imply that it is no longer legal to contact the TOTE with the CHUTE DOOR at all.
A.Good catch, apologies for our incomplete edit to G6. G6 will be updated to accommodate the normal operation of the CHUTE and CHUTE DOOR in Team Update 2015-01-30, which makes it consistent with the answer provided in [Q164].
Q164
Is the chute door allowed to contact the tote as the tote is entering the playing field? If so, can the human player control/touch the chute door while the tote is entering the field?
A.There is no restriction on when / where the CHUTE DOOR can contact a TOTE. However, please keep in mind G6: "A single ALLIANCE member may not be in contact with both a TOTE and the CHUTE DOOR simultaneously." Also consider G6-1: "G6-1 DRIVE TEAMS may not use any object to prop the CHUTE DOOR open." which would prohibit actions such as using a TOTE to prop the CHUTE DOOR open in order to feed multiple TOTES through the TOTE CHUTE without operating the CHUTE DOOR. Depending on the actions of the HUMAN PLAYER or DRIVER, G16 (FIELD damage) may be enforced if the CHUTE DOOR or TOTES are being damaged by the method.
