heres part of my camera cctv switcher to show what i was talking about regarding the use of a 4093.........the circuit also caters for switchbounce removal.
You could use a 555 in monostable operation with a very low frequency, and connect the 555 to the 4017's clock input. Then use all the LEDs you need on the Q0-Q9 outputs, and connect the last output (if use 2 leds, connect 2 of them on Q0 and Q1, and conect Q2 to reset that way it resets and only goes through the sequence of flashing 2 LEDS). There you go that may work, dunno I hardly use 555 in monostable.
