Repalcing Ignition Switch Help

Hi all,  sorry in advance for the long post....here goes....

I am currently in the process of re-wiring my 1969 VW beetle and want to replace the stock ignition switch with a combination of toggle switches and realys and was wondering if my theory here is sound...The original switch is getting a little tired and rather than replace it, I wanted to do something a little different!

I want to use 2 toggle switches (1 for Accessory position and 1 for Ignition circuit) and a momentary push button switch for the start circuit to mimic the ignition siwtch.   All 12v battery feeds will be be run through a seperate kill switch to isolate the toggle switch feeds and 12v battery common relay inputs...(effectively like using a key for the ignition switch). All switches are from ignited performance....the kill switch is rated at 500amps, toggle switches are rated at 10amps and the push button starter switch is rated at 10amps. All relays are SPDT, 12VDC 30amps from local auto parts store.

So for accessory circuit, my wiring would be like this:  12v low current feed switched through toggle switch to relay coil term 85 to energize relay coil. Relay term 86 to ground.  12v High current fused battery feed to relay common term 30. N/O relay term 87 to accesory wire, (accesory circuit of vehice wiring)

For the ignition circuit, wiring would be like this: 12v low current feed switched though toggle switch to relay coil term 85 to energize relay coil.. Relay term 86 to ground. 12v high current fused battery feed to relay common term 30. N/O relay term 87 to ignition wire (ignition circuit of vehicle wiring).

For the start circuit, I only want the push button starter switch to be able to engage if the ignition toggle is in the "on" position....so wiring would be like this: 12v low current feed from output of ignition toggle switch, through the momentary push button switch to relay term 85 to energize relay coil. Relay term 86 to ground. 12v high current fused battery feed to relay common term 30. N/O relay term 87 to starter wire (starter solenoid)

Does all this sound OK? How safe woudl this be...ie: how reliable are relays in this type of situation?  Can I daisy chain all my common battery feeds to each relay (term 30) back to one point, and all my relay coil grounds (term 86) back to one point also?

Thanks in advance for reading my post, and any advice/suggestions offered.

Anybody have any ideas on this?
